BRITISH & IRISH STANDARDS:

 Where no specific instruction is given, reference should be made to the relevant British and/or Irish

Standard codes of Practice.

 BS7074:1 Code of practice for domestic and hot water supply
 EN12828 Central heating for domestic premises
 BS7593 Treatment of water in domestic hot water central heating systems
 ECTI National rules for electrical installations

CAUTION: ISOLATE THE MAINS SUPPLIES BEFORE STARTING ANY WORK AND OBSERVE ALL RELEVANT SAFETY
PRECAUTIONS.

Danger of short circuit: When connecting the cables ensure that no cable pieces fall inside the control panel.

The Mains supply to the appliance must be through a fused double pole isolator situated next to the appliance. The isolator must have a
contact separation of 3mm minimum in all poles and should isolate the appliance and all associated controls.

Unless otherwise stated, all Heat Interface Units should be connected to a mains 230V 50Hz Supply fused at 3 Amps.

All electrical connections with the Heat Interface Unit control panel are clearly marked as follows:

 L = Live 230V
 N = Neutral

 E = Earth 

Any additional mains cable should comply fully with the current I.E.E. wiring regulations. It must have a minimum section of 0.75mm

2

and be capable of withstanding a minimum of 85C.
